A former Guam Police Department officer convicted of raping a prostitute will have to register as a sex offender and cannot possess any firearms, as ordered by a Superior Court of Guam judge.

Paul John Santos, 50, was sentenced to 21 years in prison for rape, abetting prostitution, official misconduct and other crimes.

Santos in 2014 contacted the woman, who had advertised sexual services on Craigslist, and went to her hotel room wearing his GPD uniform. He told the woman that if he took her to jail she would never see her family and said, “We’ll work something out,” before he told her to undress and raped her, court documents state.

The woman’s told her family about the assault and they called the FBI. Hotel surveillance footage helped authorities identify Santos as the officer at her hotel room.
